Does the "save playlist" plugin no longer work with the beta version since the playlist are now stored in the database?

On my Squeezebox2 I used the plugin "save playlist" and selected a name (test) to store the playlist. Then I switched to Internet Radio. After that I wanted to reload the stored playlist but it is not shown in the "browse playlist" menu. In SlimServer the playlist is also not shown but in my playlist directory on disk there is now a file "test.m3u" stored.
